|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Changes Tom
|
|
* if user left accidentally floppy or CD in drive,
|
|
give him a chance to continue to boot from HD.
|
|
disabled by default, enablable by SYS CONFIG
|
|
(BOOTHARDDISKSECONDS)
|
|
+ Changes Lixing Yuan
|
|
* dosnames.c cleanup, fix for truename if the filename
|
|
contains wildcards and a trailing dot.
|
|
+ Changes Eric Auer
|
|
* add sanity check to initdisk.c for (driveParam->chs.Sector == 0)
|
|
+ some display tweaks
|
|
* add EECHO (echo with $=ESC) support to the config.sys parser.
|
|
* distinguish between the builtin DOS version and the settable
|
|
DOS version.
|
|
* console.asm now accepts extended scancodes (modified by Bart)
|
|
* added BOOTONLY option to SYS (modified by Bart)
|
|
+ Changes David Bolen
|
|
* add support for UNC-style paths (that start with "\\")
|
|
+ Changes Luchezar Georgiev
|
|
* add Bulgarian country structure data
|
|
+ Changes Bart
|
|
* flip some slashes in drivers/*.asm
|
|
(enables cross-assembly on Linux)
|
|
* remove superfluous printf("\n") in patchobj.c
|
|
* combine the INIT class with the CODE class (classes can span
|
|
multiple physical segments)
|
|
* re-add _TEXT to LGROUP to be able to simplify the patchobj magic
|
|
* don't specify -zPI_GROUP for the init code in Borland compilers
|
|
(unnecessary, it will be put there because of segs.inc)
|
|
* remove STDPATCH; it is no longer necessary
|
|
* add FILESHIGH, LASTDRIVEHIGH, and STACKSHIGH and DOSDATA=UMB
|
|
to load these structures into UMBs
|
|
* make DOS sub-MCBs visible (seen by MEM)
|
|
* preliminary allocation of FILES etc. now takes place at the
|
|
top of conventional memory, and device drivers are loaded before
|
|
the final allocation takes place.
|
|
* handle multiple UMBs more correctly (but config.sys can use
|
|
only one UMB for devicehigh -- /Ln,xxxx is not yet implemented)
|
|
* minor size optimizations in newstuff.c, chario.c, dosfns.c and fcbfns.c.
|
|
asmsupt.asm: correct fmemchr (all n's) and *memset/*memcpy
|
|
(n==0)
|
|
* introduce lol structure for list of lists; avoid lots of
|
|
relocations
|
|
* avoid more relocations in the asm files by loading ds from
|
|
[cs:_DGROUP_]
|
|
* Fix problem with attributes with the volume label bit + findnext
|
|
* SYS: avoid copying kernel.sys and command.com if the destination
|
|
is identical to the source.
|
|
* Fix bug in DeleteBlockInBufferCache: needs to make the block
|
|
invalid, not flush it, if we're writing.
|
|
* added switches=/k/n/f support to the config.sys parser.
|
|
2003 Mar 14 - Build 2029
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Changes Tom
|
|
* fattab.c, fat.h removed the wrong ELSE_ISFAT32()
|
|
* fatfs.c: rmdir would crash if you rmdir'ed an existing file
|
|
* config.c, main.c, portab.h
|
|
implement INSTALL and INSTALLHIGH for config.sys
|
|
basic COUNTRY=xxx support (with a little help from others,
|
|
mentioned in config.c)
|
|
* execrh.asm: save si, di for strategy device driver handler
|
|
* (adjusted by Bart): the internal "truename" has to reject
|
|
wildcards for all commands except for the exposed "truename"
|
|
(DosTrueName, int21/ah=60), FindFirst and FCB functions.
|
|
+ Changes Bart
|
|
* add top level makefile with list of files to zip for releases
|
|
* remove obsolete documentation and intr.h
|
|
* eliminated the "f_highwater" fnode field.
|
|
* reintroduced HMA_TEXT segment and adjust segments in libm.lib
|
|
to solve problems with Borland compilers.
|
|
2002 Dec 9 - Build 2028
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Changes Tom
|
|
* move clock driver initialization to inittext
|
|
* new ELSE_ISFAT16 macro to save some bytes
|
|
* use _TEXT for old HMA_TEXT, _LOWTEXT for old _TEXT to get
|
|
a slightly less complicated memory model from the C compiler's
|
|
point of view.
|
|
* add support for int2f/4a01,4a02: query/allocate HMA space.
|
|
* updated config.txt
|
|
+ Changes Arkady V. Belousov
|
|
* slightly improved asm for print_hex and int2f clear_ax stuff
|
|
* use #error for unknown compilers
|
|
* remove hexDigits reference
|
|
* correct comment in kernel.asm (pad to 05fdh)
|
|
+ Changes Bart
|
|
* fix ss:sp init bug for int21/ax=4b01 (visible in DEBUG)
|
|
* fix redirection problem for character output routines
|
|
* fix press the any key message for floppy swaps
|
|
* correct cluster value for BAD cluster
|
|
* correct FAT12/16/32 cutoff magic values as per the MS spec
|
|
* the BUFFERS structure is now the same as in MSDOS 5+ and uses
|
|
a circular double-linked list using near pointers.
|
|
* move all old RCS log messages into one seperate file
|
|
* divide the fnode f_cluster_offset field by the size of a cluster:
|
|
this gives a more efficient map_cluster().
|
|
* point the CharMapSrvc pointer to the DOS DS for AARD compliance.
|
|
* nls.c: set CX to cooperate with load_unf.exe
|
|
2002 Nov 9 - Build 2027
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Changes Tom
|
|
* memset ErrorAlreadyPrinted to 0 in config.c
|
|
+ Changes Bart
|
|
* reset drive before and after int26 in SYS for winnt compatibility
|
|
* propagate sharing bits correctly in DosOpen
|
|
* return DE_NFILES if a volume label is not found; search for volume
|
|
label if attr & 8 not just if attr==8
|
|
* initialize the critical error code to 0 in inthndlr.c
|
|
* ignore value of DH for extended open int21/ah=6c
|
|
* fix problem with NULL device code being in the wrong segment
|
|
* Hopefully innocent hack to deal with NDN in ioctl.c (ignore upper bits
|
|
of the drive number)
|
|
* use subst bit 15 for int21/ax=4409(IOCTL-CHECK IF BLOCK DEVICE REMOTE).
|
|
2002 Oct 27 - Build 2027rc
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Changes Bart
|
|
* reorganized chario.c, got F1-F6, Ins, Del, etc. working
|
|
* fixed bug in extended open
|
|
* fixed bug in memory manager (realloc should try to defragment;
|
|
UMB fixes)
|
|
* consistently pass sft_idx around for all SFT functions (instead of
|
|
the far pointer)
|
|
* lpUserStack is gone :)
|
|
* Idle interrupt: now uses disk i/o stack instead of error stack if it
|
|
re-enters DOS; can not be called from int21/ah=3f. It also checks
|
|
InDos now (as documented in "undocumented dos").
|
|
* int21/ah=59 should use the disk i/o stack, not the character stack.
|
|
* get_cds: a uniform way to get the CDS for drive X which can do error
|
|
checking too. get_dpb: similar.
|
|
* task.c uses mid-level system file handles instead of PSP handles.
|
|
* SFT sequence is MS/DR DOS like: 0=AUX 1=CON 2=PRN
|
|
* int21/ah=4d needs to clear the return code after returning it.
|
|
* Removed need for "unusedretval" because some functions return a long int
|
|
now.
|
|
* Do not warn for some additional LBA partition layouts (begin/end
|
|
cylinder=1023) in initdisk.c.
|
|
* support int2f/ax=1213 (uppercase character) (ASCII only for now).
|
|
* fix for top of memory parameter to device driver - fixes problem
|
|
with DRDOS emm386
|
|
* eliminated printf for non-init code -- use put_unsigned and
|
|
put_string instead
|
|
* better MK_FP for Turbo C++ 1.01 and later
|
|
* PSP related task.c cleanups
|
|
* use --best and new upx (1.23) for binary build
|
|
Changes Tom and Bart:
|
|
* Use Pascal calling convention for memcpy and friends in asmsupt.asm
|
|
* Fixed make temp file
|
|
* fix bug in DosFindNext
|
|
* misc makefile fixes
|
|
2002 Aug 3 - Build 2027test
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Changes Tom
|
|
* enable LBA FAT16 booting
|
|
* workaround for redirectors that do/do not set the opencount
|
|
* int25/26 should fail for redirectors
|
|
* set the number of sectors per track in the INT 1E table when
|
|
reading/writing floppies
|
|
* disabled fatal() in error.c
|
|
* Disable the A20 line upon exec (int21/ah=4B). This is necessary for some
|
|
brain-dead exepacked programs.
|
|
* removed unnecessary "BUFFERS" fields
|
|
* proper check for network/non-existing drive for int25/26.
|
|
* save more bytes on the stack at various places
|
|
* made the local registers for inthndlr.c "near" instead of "far".
|
|
* fix bug in strchr handling for fcbfns.c (FcbParseFname)
|
|
+ Changes Steffen (but changed a lot by Bart)
|
|
* new truename (Bart: but without mapPath() style struct)
|
|
* merge open/create functions into one extended open function
|
|
* also honor the sharing bits better for "open"
|
|
* use local 8+3 path names in fatfs.c; merge name+extension
|
|
into one array
|
|
* take care of filenames that start with ASCII 5: they should be
|
|
treated as starting with 0xe5
|
|
* exploit the fact that the filenames are already "truenames",
|
|
i.e., fully qualified in fatfs.c. This simplifies parsing a lot.
|
|
+ Changes Bart
|
|
* make "if exist c:\dir\nul" working
|
|
* honor "do not inherit handle on exec" flag for "open".
|
|
* improve the FCB functions so that they set the critical error code
|
|
properly
|
|
* next_cluster returns "1" instead of DE_xxx in case of failure.
|
|
* create one function to do binary character IO (used for CLOCK$
|
|
driver and character drivers such as CON)
|
|
* better handling of ABORT/FAIL
|
|
* merge all read and write functions
|
|
* patchobj makefile correction
|
|
* printf uses va_list etc.
|
|
* quicker and more robust Watcom build
|
|
* use FS: and GS: for Watcom 386.
|
|
* workaround: don't use DL for floppy boots, but fixed A:
|
|
* disable unused functions in floppy.asm
|
|
* cleaner prototypes (thanks to gcc)
|
|
* reorganized ioctl.c; there was an uninitialized variable.
|
|
* inlined some functions of fattab.c
|
|
* added (f)strcmp, (f)memcmp and (f)memchr to asmsupt.asm
|
|
* initially suggested by Arkady: dsk.c FS_info copy optimization
|
|
* initialize a VDISK signature in the HMA
|
|
* sysclk.c: small size optimization
|
|
* small UMB fixes
|
|
* made the CDS into a proper array instead of a structure with
|
|
one member
|
|
* large task.c cleanups -
|
|
merge as much as possible from DosExeLoader and DosComLoader
|
|
(from Tom:) eliminate some structures in low memory
|
|
* main.c: slightly cleanup "SHELL=" line parsing.
|
|
2002 May 9 - Build 2026b
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Changes Tom
|
|
* limit output at boot time somewhat
|
|
* GetCurrentDirectory should fail, if drive is accessible
|
|
* fixed some minor config.sys parser bugs and have the possibility
|
|
of things like 123?device=EMM386.EXE NOEMS
|
|
* shorter version of DosMemLargest()
|
|
+ Changes Bart
|
|
* repaired makefile dependencies
|
|
* implemented multi-sector writes, and re-merged
|
|
readblock()/writeblock() into rwblock ()
|
|
* implemented int21/ah=1c for network drives (RHIDE needs this)
|
|
* initialize current_ldt for findnext (hinted by Steffen)
|
|
* check serial number for floppy disk changes where the drive
|
|
does not feature a changeline
|
|
* reset to root directory when floppy has changed
|
|
* cleaned up endian helpers {get,put}{byte,word,long}
|
|
* don't close file if disk is full
|
|
* enforce minimum of 9 sectors per track for INT1E (necessary for
|
|
some floppies on some XTs)
|
|
* clear carry when calling INT23 (ctrl-break handler) as per RBIL
|
|
* don't copy FCBs on exec if they are pointed to by FFFF:FFFF.
|
|
* resolved warnings for Watcom (now compiles with -wx -we)
|
|
* truename fix (return DE_FILENOTFND for foo.bar.foo)
|
|
+ Changes Jeremy
|
|
* fixed SYS _dos_getdrive for non-Borland compilers
|
|
+ Changes Tom and Bart
|
|

|
2002 Feb 17 - Build 2026a
|
|

|
|
+ Changes Martin
|
|
* fixed SYS for non-Watcom compilers
|
|
+ Changes Tom
|
|
* set CONFIG environment variable to selected number of CONFIG.SYS
|
|
menu entry, for example for use in AUTOEXEC.BAT.
|
|
+ Changes Bart
|
|
* fixed FCBOpen
|
|
* network redirector fixes ; it appears that clearing CF before calling
|
|
the redirector is safer than setting CF
|
|
* allow creating, renaming and deleting volume labels using FCBs
|
|
* fix renaming with wildcards using FCBs
|
|
* some dosfns.c and fcbfns.c clean-ups
|
|
* booting from hard disk now always sets the default drive to C:,
|
|
not D: if booting from the second physical hard disk, etc (bug #1062).
|
|
2002 Feb 9 - Build 2026
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Changes Tom
|
|
* fixed various typos, #includes
|
|
+ Changes Bart
|
|
* fixed ECHO in config.sys
|
|
* made passing parameters to command.com more robust:
|
|
zero commandline before use, fixed buffer overflow for F5+F8
|
|
* "uppermem_root" in the List of Lists is now FFFF if no UMBs
|
|
available, as documented in RBIL
|
|
* removed all direct hooks from init_text to hma_text; duplicated
|
|
the remaining functions (memset, memcpy and friends).
|
|
* bumped up default DOS version of FAT32 enabled kernel to 7.10
|
|
2002 Feb 3 - Build 2026test
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Changes Tom
|
|
* FCB clean-ups and fixes (bug in FCB Random IO,
|
|
CYRUS CHESS, bug #1014)
|
|
* initial config.sys menus (see config.txt)
|
|
* execrh.asm: construct 'interrupt' address after strategy to avoid
|
|
some issues with non-trivial 'strategy' routines.
|
|
* make kernel UPX-able
|
|
* cleaned up midnight flag, dates
|
|
* tmark() and friends are floppy specific and implemented in C
|
|
instead of ASM (parts by Bart)
|
|
* DMA boundary checking gives the right number of sectors if
|
|
the start sector is 512-bytes-aligned.
|
|
+ Changes Victor
|
|
* lfn fixes (lfn is only a place holder, does not work yet)
|
|
* FAT32 fixes
|
|
* dosemu log nicer
|
|
+ Changes Martin
|
|
* log output
|
|
* warning fixes for sys, patchobj and prf.c
|
|
+ Changes Bart
|
|
* FCB clean-ups and fixes
|
|
* make Watcom compiled kernel runnable
|
|
* make compilation with Pascal style calling conventions
|
|
for Borland compilers (-p) possible
|
|
* initialize CDS before opening devices
|
|
* implement lock/unlock for remote drives
|
|
* implement commit file (int21/ah=68,6a)
|
|
* implement ioctl get/set logical drive map (int21/ax=440E--F)
|
|
* implement get address of drive data table (int2f/ax=0803)
|
|
* fix "get address of SDA" (int21/ax=5d06)
|
|
* do not use CHS if the root extended partition of the relevant
|
|
logical partition is labelled LBA (bug #1011)
|
|
* hopefully avoid format problem (bug #1030) by not setting drive
|
|
to "non-accessible" while reading the bpb.
|
|
* boot sector fixes:
|
|
enable booting beyond cylinder x where x * number of heads >= 65536.
|
|
still uses CHS to boot (not able to boot beyond cylinder 1023)
|
|
recognize FF8-FFF as FAT12 ending (was only FFF) (bug #1021)
|
|
* avoid using LIB when linking the kernel by echo-ing to a linker
|
|
resource file. Use a batch file to bypass Borlands Make 2.0
|
|
unwillingness to redirect stdout.
|
|
* UMB variable clean-up
|
|
* use of "const" for constant global variables
|
|
* reduced size of Watcom-compiled SYS binary
|
|
2001 Nov 18 - Build 2025c
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Changes Bart
|
|
* ran source code .c and .h files through "indent"
|
|
* fixed new printf bug
|
|
* removed some duplicate documents
|
|
+ Changes Victor & Bart
|
|
* fixed sys.c fat32 detection bug (offset 0x10, not 0x2c)
|
|
2001 Nov 17 - Build 2025b
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Changes Tom
|
|
* fix a few more batch file and makefile details
|
|
* fix problems with command line editing: F1 and right key
|
|
* string merging in dosnames.c
|
|
* optimizations for MSC
|
|
+ Changes Bart
|
|
* fix readblock problem not properly detecting EOF - it sometimes
|
|
returned an error where it should just report a short count.
|
|
Also fnp->f_offset==0 is not a special case for blockread
|
|
(neither should it be for write - but that'll be for later)
|
|
For both cases it's perfectly legal to do a seek first.
|
|
* fix writeblock not setting highwater to offset when doing a
|
|
truncate (count == 0)
|
|
* hopefully now really fix the floppy change problem -
|
|
dsk.c: getbpb() should query changeline BEFORE reading the BPB.
|
|
* fixed warnings from WATCOM compiler - one of them was in fact
|
|
a bug in fcbfns.c
|
|
* started big clean-up
|
|
- converted obsolete bcopy(), sncopy() and friends to memcpy(),
|
|
strncpy() etc.
|
|
- removed $Log entries that are also on the CVS server and
|
|
removed the $ so no new entries will be added in files.
|
|
indenting will be next - other fixes will be buried in diffs if
|
|
I do that now.
|
|
2001 Nov 12 - Build 2025a
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Changes Tom
|
|
* initialize LBA parameter struct to 0's - some BIOSes don't fill
|
|
in everything. Thanks to Bernd Blaauw's bug report.
|
|
* Minor boot sector optimization.
|
|
* added some exeflat options
|
|
+ Changes Jeremy
|
|
* changes to fdkrncfg.c: mostly cosmetic to the output
|
|
* added sys.doc file (updated by Bart)
|
|
+ Changes Bart
|
|
* let int 0 (divide by zero) and int 6 (invalid opcode) print a
|
|
stack trace to aid in debugging
|
|
* fixed floppy drive detection for XT's.
|
|
* fixed bug in int21/ah=0x32 and friends - we should flush data before the
|
|
forced media_check
|
|
* Use CHS addressing if possible on partitions with the relevant ID,
|
|
you can overide this using the new FORCELBA and GLOBALENABLELBASUPPORT
|
|
sys config options.
|
|
* Always use BIOS values for translating LBA to CHS for fixed disks -
|
|
ignoring the boot sector values. For floppies the boot sector is used.
|
|
* fixed "truename hello." to remove the trailing dot.
|
|
* added options to SYS to write to a boot sector image file
|
|
* set Critical Error Code for ioctl's
|
|
* fake cluster size for 64k clusters just like FAT32 for INT21/AH=0x36
|
|
and friends.
|
|
+ Changes Bart+Tom+Victor
|
|
* make makefile system more robust
|
|
+ Changes Victor
|
|
* cleaned up map_cluster and dir_read (bug fixed by Bart)
|
|
* updated LFN API (in development, not used yet)
|
|
2001 Nov 4 - Build 2025a (test)
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Changes tom
|
|
* config.sys processing: placing ? on the left side of '=' like
|
|
?device= or device ?=
|
|
asks for this single line
|
|
fill the available HMA with buffers
|
|
* added kernel configuration options to sys.com, small area at 60:xx
|
|
(in cooperation with Jeremy)
|
|
* readblock optimized to read as many data as possible in one
|
|
int13 request - great speedups for large reads
|
|
* some more SDA variables need to be updated for the network
|
|
redirector (the sft index)
|
|
* reduce stack usage in task.c, fattab.c, ioctl.c, execrh.asm, inthndlr.c
|
|
* protect high part of 32-bit registers (stacks.inc)
|
|
* moved copyright messages to init data to save a bit of memory
|
|
* added relocinf, patchobj, sorted + some more output of exeflat
|
|
* UMB fixes
|
|
+ Fixes Bart, Victor, Tom
|
|
* more FAT32 fixes - to work with device drivers
|
|
* fixed overflow problem with more than 2048 directory entries
|
|
* various space saving changes, dir_init_fnode
|
|
+ Changes Bart, Tom
|
|
* many makefile changes to enable compilation with different
|
|
compilers (MS, Watcom, Borland). Watcom compiles but the result
|
|
does not run yet.
|
|
+ Changes Bart
|
|
* extended the double-byte lead table from int21/ah=63 to 4 zeros
|
|
to make Watcom happy
|
|
* support for IOCTL AX=440D, CL=40,41,42,61,62 for
|
|
read/write/format track - this enables R. Nordier format to work
|
|
* default floppy type depends on the drive
|
|
* rewrote many parts of int2f.asm to have a cleaner remote_xxx
|
|
interface with less code and stack usage.
|
|
* limit for int21/ah=36 is FFF6 total/free sectors
|
|
* made the rtc clock reading code a bit more robust - assumes
|
|
there is no rtc if the returned date is zero
|
|
* removed non-necessary code in dosnames.c because we're always
|
|
dealing with a TRUENAME there
|
|
* added zero extending of files, but removed it (unless you force
|
|
it) since MSDOS doesn't zero-extend files either
|
|
* wrote a source for exeflat, removed all binaries from the source
|
|
* added more INT2F/AH=12 functions to solve some MSCDEX issues
|
|
* changed BAD sector handling : only ....FF7 is recognized as BAD,
|
|
but FORMAT information from initdisk will only give ....FEF as
|
|
the largest cluster (for safety), so ....FF0-....FF6 are not used
|
|
for newly formatted disks (here .... is either nothing, F, or
|
|
FFFF, FAT12/FAT16/FAT32).
|
|
* more fatfs/fatdir clean-ups - now unnecessary fields dfull,
|
|
dremote and dsize removed from fnodes.

|
* Simplify Victor's FAT32 fixes a bit
|
|
* More printer clean-ups
|
|
* fixed sys (thanks Jeremy)
|
|
* DosChangeDir fails for path name too long.
|
|
+ Fixes Jeremy
|
|
* Changed SYS so if no source given or only source drive (no path)
|
|
given, then checks for kernel.sys & command.com in current
|
|
path (of current drive or given drive) and if not there
|
|
uses root (but only if source & destination drive are different).
|
|
Fix printf to include count(ret) if copy can't write all requested bytes

|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Added Victor
|
|
* FAT32 support (credits to Martin Stromberg for boot32.asm optimizations)
|
|
* Delete long file names if short file name given
|
|
+ Added Jeremy
|
|
* modified SYS so it takes optional 2nd parameter (similar to PC DOS)
|
|
where if only 1 argument is given, assume to be destination drive,
|
|
but if two arguments given, 1st is source (drive and/or path)
|
|
and second is destination drive

|
|
* many compiler portability changes (compiles with Watcom, MSC, ...)
|
|
* DosMemChange should set the PSP
|
|
* converted INT2F/AH=12 functions to C and added some - enough to
|
|
get most of the MS LAN network client working
|

+ fixes Bart
|
|
* some FAT32 issues
|
|
* Dos{Open,Creat}Sft drive letter issues
|
|
for CDROMs (thanks Jeremy)
|
|
* shrink_file should ALWAYS fail for directories, also with

|
dos_set_fattr (thanks Jeremy)
|
|
* only give warnings for slightly suspect partitions at boot
|
|
time where CHS does not match LBA.
|
|
* re-enabled copyright notice.
|
|
* some dsk.c clean-ups to avoid DIR giving the same contents for
|
|
a different floppy (get serial number/volume label did reset the
|
|
changed state).
|
|
* attribute should be 8-bit fix

|
|
* initdisk.c correctly sets number of hidden sectors: necessary
|
|
for FORMAT - SYS chain to work
|
|
+ updates Bart
|
|
* initialisation memory situation changed: kernel is loaded
|
|
to the top of conventional memory in the beginning. Then
|
|
move it back low or high depending on DOS=HIGH and the presence
|
|
of an XMS driver.
|
|
DOS=HIGH without an XMS driver (such as FDXMS) has no effect anymore!

* FCB corrections and cleanups (with a little help from Tom)
|
|
* cleaned up (FCB)FindFirst/FindNext a little more.
|
|
* task.c: copies default FCBs, initializes AX properly and
|
|
an int21/ax=4b01 fix. Also closes all FCB opened files upon
|
|
termination of a program.
|
|
* dosnames.c: fixed DJGPP "ls c:/" problem reported by Martin
|
|
+ fixes Victor Vlasenko
|
|

|
|
* fix for fatfs.c shrink_file()
|
|

|
|
* handle B: just like A: on a single floppy system. There still needs to be

* ioctl.c fix for INT21/AX=4400 + sft driveno field
|
|
* various small fcb fixes
|
|
* put file position number and pointers to Pri/SecPathName into

|
SDA. Now MSCDEX works as redirector (but still not always :-()
|
|
* redirector set attribute fixes + various cleanups
|
|
* truename+attr+ioctl fix => DJGPP libc compiles cleanly!
|
|
+ changes Bart
|
|
* use the output of truename() consistently: this saves a lot of
|
|
headaches in parsing later and also allows a lot of simplifying:
|
|
made many parameters in fatfs.c and fatdir.c NEAR
|
|
+ added Bart
|
|
* partly implemented the "Drive Data Table" see RBIL INT2f/AX=0803
|
|
* implemented construction of default BPB in initdisk.c

* Tab fix (bug reported by Martin Stromberg)
|
|
* INT21/AH=0x1f now simply uses AH=0x32 for the default drive
|
|
+ fixes Tom
|

* saved some static variables
|
|
* implementation of int_2f_111e_call() for network/LAN manager

2001 Jul 9 - Build 2024/d
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ fixes Bart:

* fixed Ctrl-C (Ctrl-S and Ctrl-Q still missing).
|
|
* ioctl EOF fix (DJGPP less&gdb problem reported by Martin Stromberg)
|
|
* INT21/AH=29 (Parse Filename into FCB) fix (NC problem reported
|
|
by Ken Martwick) with clean up from Tom.
|
|
* ioctl should do a media_check before calling the block driver:
|
|
this fixes bug #726 (first dir gave serial no. 1234-5678).
|
|
* initdisk.c now uses the init data segment.
|
|
+ fixes Tom:
|
|
* fixes for INT21/AH=32; this should cure the problems with
|
|
Brian's new format.
|
|
* more SYS fixes.
|
|
+ added Tom:
|
|
* some more diagnostics (123) to aid finding bugs when booting from
|
|
a hard disk.
|
|
|
|
from 2001 jun 23 : KE2024BP
|
|
|
|
+ fixes Tom:
|
|
* FAT FS: would not expand files correctly, if lseek()
|
|
beyond EOF (see also relnotes.txt)
|
|
* FcbFindFirst/Next made compatible with MSDOS CHKDSK
|
|
* saved even more bytes (now 24 buffers in HMA :-)
|
|
|
|
from KE2024BM
|
|
+ added Tom:
|
|
* a mechanism, to regain near data (like miarray, bpbarray,...)
|
|
this is somewhat braindamaging, moving the kernel up and down,
|
|
working with different CS/DS combinations, but somehow working, :-)
|
|
miarray allocated, using this mechanism.
|
|
* made f_nodes near (2 K saving in HMA_TEXT)
|
|
this technic might as well applied to CDs, DPB, sft's, ...
|
|
this even saves a few bytes on stack :-)
|
|
|
|
from 2001 May 21: Build2024L
|
|
+ Fixes Tom:
|
|
* Clustersize 64K made working (one small ULONG was missing)
|
|
* check for drive existence for INT25/26
|
|
* NDEV = max number of possible harddisk partitions bumped
|
|
from 8 to 20 (my testconfiguration has 13)
|
|
|
|
+ Added tom:
|
|
* LBA support for disks > 8GB (with the help from Brian
|
|
Reifsnyder, see also relnotes.txt)
|
|
* moved initialization for DISK (partition scanning) to INIT_CODE

2001 Jun 2 - Build 2024
|
|
-------- Bart Oldeman (bart@dosemu.org)
|

|
|
* small fixes again.
|
|
* one possible cause for data corruption (BFR_VALID) detected
|
|
* directories with 'ARCHIVE' attribute could not be deleted
|
|
* saved even more bytes (now 20 buffers in HMA :-)
|
|
* some issues with pathnames around PARSE_MAX removed
|
|
* blanks in filenames weren't proper handled
|
|
* there was (at rare circumstances) a buffer overflow
|
|
while config.sys parsing.
|
|
+ Fixes Bart:
|
|
* INT 21 0A - Dos Buffered Input reworked
|
|
* init_PSPSet() fix for setting the PSP
|
|
+ Added tom:
|
|
* slighly better buffer handling (search BFR_UNCACHE)
|
|
now go more FAT+DIR sectors, less DATA sectors into cache
|
|
* dos_mkdir tuned (was ~0.5 sec on 64K cluster partitions)
|
|
|
|
2001 Apr 29 - Build 2024
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Fixes Bart:
|
|
* fixed the "TYPE > FOO.TXT" poor man's editor.
|
|
* use "fast console output" (int 29) when applicable.
|
|
* moved 5 FILES to DOS DS:00CC and fixed the SFT linked list.
|
|
* cleaned up findfirst/findnext for redirected drives.
|
|
Tom:
|
|
* more VDISK changes (changed slightly by Bart)
|
|
* check for presence of A:/B: (changed by Bart to use the BIOS equipment flag
|
|
from INT11 instead of INT13).
|
|
* added F5/F8 stepping through config.sys; default SHELL=COMMAND.COM /P/E:256
|
|
Use ESC to stop single stepping, F5 to skip remaining config.sys/autoexec.bat.
|
|
* new sys: uses INT25/26 instead of the low level INT13 related kernel code from
|
|
floppy.asm (see also comments in sys.c) + a few fixes (also boot.asm related)
|
|
from Bart.
|
|
* Hopefully fixed DateTime Changed + ATTRIB |= ARCHIVE bug.
|
|
* cleaned up dsk.c and saved more bytes.
|
|
Przemyslaw Czerpak:
|
|
* Default lastdrive should be 5 (E) not 6 (F).
|
|
* fixed not ignoring whitespace after '=' in config.sys
|
|
* noted INT21/AX=3800 bug for getting the country. Put in a workaround for now.
|
|
2001 Apr 21 - Build 2024
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Fixes Tom:
|
|
* fixed a missing close_dir in fatfs.c.
|
|
* many reductions of stack space requirements.
|
|
we hope this fixes some FAT corruption problems.
|
|
Bart:
|
|
* fixed "copy con" and INT21/AH=0B. The SFT_FEOF flag,
|
|
strangely enough, if true indicates NOT end-of-file.
|
|
* VDISK signature required in HMA (bug 701 dborca@usa.net).
|
|
Alan Kamrowski
|
|
* fixed intr: it wasn't putting the flags back correctly
|
|
and swapped si and bp.
|
|
+ Update Bart:
|
|
* Changed initialization data segment to its code segment.
|
|
This frees up a few more kb.
|
|
* This required some header reorganisation:
|
|
init-mod.h is for the init modules, globals.h for all the
|
|
others.
|
|
* Eliminated the master environment, as it is normally
|
|
managed by command.com, not by the kernel. This saves 512
|
|
bytes and command.com now copies a default environment from
|
|
0068:0000; this is in the DOS_PSP at 60:0.
|
|
* Moved low memory code segment to 70:0.
|
|
+ Add Tom:
|
|
* Default interrupt 6 handler (invalid opcode).
|
|
2001 Apr 16 - Build 2024
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Fixes * Use turboc.cfg to avoid long command lines; edit ALLCFLAGS

|
in config.mak to enable DEBUG etc.
|
|
* Fixed critical error handler.
|
|
* Fixed loading .exe's in UMBs if not enough space available.
|
|
* Some device drivers require \r\n at the end of their
|
|
parameter line.
|
|
2001 Apr 16 - Build 2023
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Fixes * Thanks to Martin Stromberg for pointing some bugs out:
|
|
* more warnings fixed.
|
|
* accidentally opened too many file handles at boot time.
|
|
* device drivers should not be linked into the device chain
|
|
if they do not take up memory.
|
|
+ Add * added printf "%S" and "%Fs" to print far strings.
|
|
* enabled and cleaned up INT21/AH=6C (extended open/create).
|
|
2001 Apr 15 - Build 2023
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Fixes Tom:
|
|
* apisupt.asm not necessary anymore.
|
|
* fix warnings.
|
|
* Don't allow directories to be created in DOS_CREAT.
|
|
* LoadDevice: drivers should not hang the computer if they fail.
|
|
Bart:
|
|
* fixed SYS.
|
|
* made most calls near again, with a jump/stack trick to
|
|
switch between INIT_TEXT and HMA_TEXT.
|
|
* INIT_TEXT now calls INT21 itself for some things (setting
|
|
PSP, opening/reading/closing devices and (fd)config.sys).
|
|
* fixed some carry handling in inthndlr.c and
|
|
* drives are checked before trying to access them.
|
|
* fixed console driver "busy state" confusion: the built-in
|
|
driver had it wrong, nansi.sys had it right:
|
|
"If no characters in buffer, return BUSY".
|
|
* space savings (RTL related and various other places)
|
|
* redirector fixes for find_next.
|
|
* CREAT on a device file failed (FD said it already existed).
|
|
But for some reason it should not fail in DOS.
|
|
* get ATTRIB/other things on a device file should return
|
|
FILENOTFOUND, not PATHNOTFOUND.
|
|
The sft_status field is not used for redirected drives.
|
|
* DosSelectDrv checks the media before setting the default
|
|
drive.
|
|
* Fixed INT21/AH=3,4,5 (character R/W AUX/PRN).
|
|
Hans Lermen:
|
|
* critical error handler destroyed AH (entry.asm).
|
|
Martin Stromberg
|
|
* find_first for volume labels fix.
|
|
* check drive at more places and avoid drive "@:" for drive "':".
|
|
* config.m: comment out NASM= by default.
|
|
* printf fix with DEBUG on.
|
|
+ Add Tom: Introduce init_data segment.
|
|
New temp file creation implementation.
|
|
Bart: added INT21/AH=53. XMSDSK works fine now.
|
|
dynamic allocation of Drive Parameter Blocks (they are
|
|
all FAR now).
|
|
+ Update Bart: moved DOS_PSP to segment 0x60 as segment 0x50 is already used by
|
|
GWBASIC/BASICA
|
|
|
|
2001 Apr 2 - Build 2023
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Fixes Bart: Volkov Commander revealed a few bugs:
|
|
-int 21/ah=55 forgot to set current psp to child psp.
|
|
-memory allocation: mem_access_mode was a signed byte, and hence 0x80 was
|
|
translated to 0xff80 and not 0x0080 when converting to a COUNT. Hence
|
|
changed it to become a UBYTE.
|
|
-An error in memmgr.c: search again in low mem for modes 0x80,81,82, not
|
|
0x40,0x41,0x42
|
|
* execrh.asm & int2f.asm: made code executable on a 8088 (no push
|
|
constant)
|
|
* entry.asm: made sure dos_crit_sect is executed when required to.
|
|
* Another redirector fix. int 2f/1122 needed DS=current psp. This caused a
|
|
bug for me: after compiling FreeCOM on a redirected drive "dir" did not
|
|
work any more.
|
|
* The nansi.sys problem: as it was, the initialisation phase of nansi
|
|
called int/ah=30, which checked control-break, which checks the console
|
|
driver, which at that point is the still not initialized nansi. This
|
|
messed up the request header passed to it. A solution I found is to link
|
|
a device into the device chain _after_ initialisation, not before.
|
|
* Redirector fix: network.c uses fmemcpy instead of fsncopy.
|
|
* Fixed INT 21/AH=6 (direct console input).
|
|
Tom:
|
|
* DE_NFILES instead of DE_FILENOTFOUND to allow Volkov Commander to browse empty
|
|
drives.
|
|
* Fixed bug wrt zero terminated device names (should be spaces terminated).

2001 Mar 30 - Build 2023
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Fixes Tom: Kernel alloc initialises to 0. This avoids some weird errors.
|
|
Implemented default divide by 0 handler (INT 0)
|

FILES= fixes from config.sys. fatfs.c ignored it and always
|
|
used the default of 16.
|
|
Misc debug code removal.
|

int 21/ax=3306 report running HIGH fix.
|
|
int 21/ah=69 : save CX

|
|
Suggestions from Martin Stromberg: warning removal and some
|
|
debugging related changes.
|
|
Suggestion from Aitor Santamaria Merino: implemented NUMLOCK=ON/OFF
|

2001 Mar 21 - Build 2022
|
|
-------- Bart Oldeman (bart@dosemu.org)
|
|
+ Clean A lot of space savings by Tom Ehlert, merely because Turbo C 2.01 does not
|
|
do it. And several more complicated situations as well, like coding some
|
|
string functions in assembly (asmsupt.asm).
|
|
+ Add Tom Ehlert: support for DOS=HIGH. Now most of the kernel can be loaded into
|
|
the HMA. This required a lot of segmentation changes. Let's hope the best
|
|
of it. Support for device drivers with multiple devices.
|
|
+ Fixes From Tom Ehlert:
|
|
task.c bug fix (image_size is in bytes)
|
|
dosfns.c change dir to E:\FREEDOS\*.PRJ fix
|
|
fcbfns.c fixes.
|
|
break.c Ctrl-C Ctrl-C -> crash temporary fix.
|
|
+ Fixes From Bart:
|
|
Let UMBs work again after HMA changes.
|
|
Be able to compile sys.com again. Is now really a .exe file but still masks
|
|
as .com in the hope that we can make it a real .com again.
|
|
DeviceHigh loads low if there are not enough UMB's available.
|
|
Fixed another redirector problem.
|
|
+ Update Optimized asmsupt.asm a bit with help of the glibc 2.2 source.
|
|
+ Fixes Tom Ehlert and Brian Reifsnyder: fix partition detection in dsk.c +
|
|
other bug fixes (also: floppy.asm).

|
2000/08/12 22:49:00 Ron Cemer (roncemer@gte.net)
|
|
Fixed writeblock() to only use getbuf() if writing a
|
|
complete sector; otherwise use getbloc() and do a
|
|
read-modify-write to prevent writing garbage back
|
|
over pre-existing data in the file.
|
|
This was a major BUG.

+ Fix Bart Oldeman (bart@dosemu.org) found bugs with copy
|
|
command using Dosemu Lredir. Fixed Dosfns return for ReadCount,
|
|
WriteCount and DosGetFattr. Fixed the return in int2f.asm for
|
|
Read/Write Remote. By adding xor ax,ax.
|

|
-------- James Tabor (jimtabor@infohwy.com)
|
|
+ Fixed IsDevice is used in FcbFns.c and DosFns.c. I removed IsDevice
|
|
from DosNames.c an placed it in DosFns.c. FcbFns had dup code
|
|
and it was removed. This fixed all the functions using IsDevice.
|
|
|
|
Truename works now. I consider it dangerous and brain damaged.
|
|
Note:
|
|
truename X:\DIR\con -> X:/CON, note the '/'.
|
|
truename foo*.* -> X:\DIR\FOO?????.???
|
|
truename *.*\*.*\*.* -> ????????.???\????????.???\????????.???
|
|
truename *.*\*.**\*.* -> endless Loop
|
|
I will fix this later ;^)

|
|
+ -------- Eric Biederman
|
|
+ Fixed Lastdrive handling
|
|
+ Fixed Not enough drives for number present devices
|
|
+ Added Working (though not perfect network redirector)
|
|
Note: Error codes internal to freedos are negative
|
|
Error codes external to freedos are postive.
|
|
The network redirector is external to freedos...
|
|
Note: Running the nonredirected functions on a redirected
|
|
drive is dangerous. My patch is very careful
|
|
not to. Except in truename. Where (a) it is safe
|
|
and (b) I think it is required, and (c) it is needed
|
|
by dosemu.

-------- Steffen Kaiser (Steffen.Kaiser@fh-rhein-sieg.de)
|
|
+ Fixed Config.c COUNTRY= statement
|
|
+ Fixed *.c to call upFMem() when upcasing filenames
|
|
- Removed everything to load NLS into memory
|
|
= Redesigned hardcoded NLS information
|
|
|
|
--> The kernel will now return the proper information for the
|
|
hardcoded NLS (U.S.A. / CP437), it would return the correct
|
|
information for other NLS, too, if there would be a NLSFUNC
|
|
available, which is not at this time.
|
|
|
|
NOTE: The way the external NLSFUNC is called does not look well,
|
|
therfore expect a change soon.
|
|
|
|
2000 Mar 15 - Build 2019
|
|
-------- James Tabor (jimtabor@infohwy.com)
|
|
* Dennis Newbold and Massimo De Munari email kernel bug reports
|
|
with changes to Globals.h and Inthndlr.c. Fix to leap year and
|
|
Delete file return code.
|
|
* Michal Meller found a bug in media_check. It return the wrong
|
|
value of sector count. Change in FATFS.C.
|
|
* Fixed Func 0x32 based on information from Marty <k3pbu@arrl.net>.
|
|
Func 0x32 Get Drive Parameter BLK did not work.
|
|
|
|
2000 Mar 09 - Build 2018
|
|
-------- James Tabor (jimtabor@infohwy.com)
|
|
Added CDS and made FD CDS based. Changes encompass all of the
|
|
code for FD.
|
|
Fixed Task.c, rewritten code from FINODE to SFT function calls.
|
|
Unable to execute from CD. Main.c and Config.c has small
|
|
changes.
|
|
Fixed Device drivers are unable to write to con. Rewritten code to
|
|
relocate DOS_PSP pointer to 050:0000. Removed references to
|
|
DOS_PSP in DosFns.c.
|
|
Added Network and Redirection function calls in Inthndlr.c and
|
|
network.c.
|
|
|
|
I have a note in FatFs.c line 313, describing functions not yet
|
|
supported for networking. I don't understand Pats thoughts on SFT to
|
|
FINODE. IMHO it would have been easier to stay with SFT all through
|
|
the code.
|
|
|
|
I tested MS-Dos 6.22 Command and found it unable to do Find First or
|
|
Next. This too could explain why MSCDEX does the same thing. I only
|
|
test this with the current FDCommand at the time, so this could have
|
|
changed.
|
|
|
|
1999 Sep 24 - Build 2017
|
|
-------- John Price (linux-guru@gcfl.net)
|
|
* Per Jens Horstmeier's email, changed boot sector code to make
|
|
Siemens CDROM's bootable. The changes should be OK for all other
|
|
machines too (in theory).
|
|
|
|
1999 Sep 22 - Build 2016
|
|
-------- John Price (linux-guru@gcfl.net)
|
|
* Turned off debug output from the kernel. It does not seem to be
|
|
necessary at this time.
|
|
* Changed boot sector to do single-sector reads instead of
|
|
multi-sector reads. Appearantly this was part of the reason the
|
|
kernel would not boot from a 720K, or other format floppies. Thanx
|
|
to Charles Dye for the info.
|
|
|
|
1999 Sep 16 - Build 2016
|
|
-------- James Tabor (jimtabor@infohwy.com)
|
|
* Added Networking and Server Call
|
|
* Added Dos Idle call
|
|
* fixed Console.asm ConInStat
|
|
|
|
1999 Sep 13 - Build 2014
|
|
-------- John Price (linux-guru@gcfl.net)
|
|
* Deleted some files from the drivers directory that were not being
|
|
used.
|
|
* Changed the LIB.MAK file so it would work for TC2 or TC3 or higher.
|
|
* Changed SYS.COM so that it creates a sys.log file with more debug
|
|
information to help debug problems with making boot disks.
|
|
|
|
1999 Sep 13 - Build 2014
|
|
-------- James Tabor (jimtabor@infohwy.com)
|
|
* Submitted changes to CONSOLE.ASM & INTHNDLR.ASM to fix the INT21
|
|
func 0B bug.
|
|
|
|
1999 Sep 13 - Build 2014
|
|
-------- Helmut Fritsch (helmut.fritsch@gcd-hs.de)
|
|
* Submitted changes to CONSOLE.ASM to fix the INT21 func 0B bug.
|
|
|
|
1999 Sep 10 - Build 2014
|
|
-------- ror4 (f2xm1@crosswinds.net)
|
|
* At the suggestion of Mr John Price, modified the int 0x25 and int
|
|
0x26 so that they no longer update the disk buffers (int 0x26 only
|
|
invalidates the buffers for the specified drive). This is to avoid
|
|
inconsistent disk buffers from appearing in the buffer chain due to
|
|
interactions between int 0x25/0x26 and file read/write operations.
|
|
|
|
1999 Aug 24 - Build 2013
|
|
-------- John Price (linux-guru@gcfl.net)
|
|
* With ideas from ror4, I redid the build batch file so you can
|
|
specify where what make to use.
|
|
* Also created CONFIG.M and CONFIG.B which should be copied to
|
|
CONFIG.MAK and CONFIG.BAT, respecively, and edited to reflect the
|
|
users configuration. This keeps new versions from replacing the
|
|
configuration files so the user does not have to keep reseting
|
|
their configutation.
|
|
|
|
1999 Aug 15 - Build 2013
|
|
-------- ror4 (ror4@angelfire.com)
|
|
* Patched the source so that it can be compiled with Turbo C 2.01.
|
|
(`asm' statements were rewritten into very ugly equivalents... they
|
|
probably need more work. :( )
|
|
* Modified the `dmatch' structure in `hdr/dirmatch.h' so that the
|
|
`dm_dirstart' field is in the right place, and also to make it
|
|
compile under TC 2.01, which doesn't allow bit fields of any types
|
|
other than signed or unsigned int.
|
|
* Fixed a few minor bugs in error code returning in `kernel/fatfs.c'.
|
|
|
|
1999 Jul 16 - Build 2012
|
|
-------- ror4 (ror4@iname.com)
|
|
* Finally ported all the assembly modules to `nasm'. *phew*
|
|
* Undid plonee's patches to `kernel/fatfs.c' (sorry). They were
|
|
causing the resulting findfirst/findnext DTA structures to be
|
|
incompatible with MSDOS's.
|
|
* Also rewrote all the pattern copying code in `dos_findfirst' in
|
|
`kernel/fatdir.c' to prevent a bad buffer overflow problem.
|
|
* Modified the disk buffer handling code, so that logical sector
|
|
numbers in disk buffers are now 0-based instead of 1-based.
|
|
* int 0x25 and int 0x26 now do multi-sector reads/writes.
|
|
|
|
1999 Jul 14 - Build 2012
|
|
-------- ror4 (ror4@iname.com)
|
|
* Ported the modules in the `drivers/' branch to `nasm'.
|
|
|
|
1999 May 04 - Build 2011
|
|
-------- ror4 (ror4@cryogen.com)
|
|
* Fixed the code for converting day numbers into Julian calendar
|
|
dates: the first and last days of each month are now returned
|
|
correctly.
|
|
* Undid a change to the code to get the day of the week.
|
|
|
|
1999 May 02 - Build 2011
|
|
-------- John Price (linux-guru@gcfl.net)
|
|
* blockio.c: changed getblock and getbuf so that they leave at least
|
|
3 FAT type buffers valid. This helps because the FAT is accessed
|
|
very often compared to other sectors.
|
|
* fatfs.c: Fixed a bug in map_cluster so it will optimize FAT reads
|
|
on disks that have more than one sector per cluster. This
|
|
sigificantly improved disk access of big files on hard drives.
|
|
|
|
1999 May 02 - Build 2011
|
|
-------- ror4 (ror4@cryogen.com)
|
|
* Corrected the `struct buffer' definition in `kernel/globals.h' so
|
|
that it corresponds exactly to Ralf Brown's description of a DOS 3.x
|
|
buffer.
|
|
* Also fixed the problem with FATs > 255 sectors, by making use of an
|
|
originally unused field in the buffer structure.
|
|
|
|
1999 May 01 - Build 2011
|
|
-------- ror4 (ror4@cryogen.com)
|
|
* Fixed a problem which caused disk corruption on partitions with
|
|
FATs larger than 127 sectors. (However, FATs larger than 255
|
|
sectors may still experience problems -- this is due to a
|
|
limitation of the DOS 3.x buffering scheme.)
|
|
* Fixed a bug in the handling of the `stacks=' command in
|
|
`(fd)config.sys' which caused the system to behave strangely.
|
|
|
|
1999 Apr 22 - Build 2011

|
-------- Steffen Kaiser (Steffen.Kaiser@fh-rhein-sieg.de)
|
|
bugfix: memmgr.c: Invalid returned largest size in MemLargest()
|
|
fix: memmgr.c: DosMemLargest: change prototype to match its useage
|
|
bugfix: inthdlr.c: 0x49: ES is decremented
|
|
fix: inthdlr.c: 0x00: DosMemCheck() does nothing --> added panic()
|
|
fix: inthdlr.c: 0x4c: DosMemCheck() does nothing --> added panic()
|
|
fix: inthdlr.c: 0x00: changed to make it the same as DOS-4C-00
|
|
Both actions differed e.g. in ErrorMode
|
|
chg: memmgr.c: the 'name' field of the MCB is never initialized by
|
|
DOS-48, DOS-49 or DOS-4A. Leave this to the program loading function.
|
|
bugfix: memmgr.c: adjust_far() / add_far():
|
|
Both function together (and the way they are used) don't make sense:
|
|
adjust_far() normalizes a far pointer, add_far() generates a linear
|
|
address. Usually both are used this way:
|
|
far_poi = adjust_far(far_poi);
|
|
while(...) {
|
|
...
|
|
far_poi = add_far(far_poi, uword);
|
|
...
|
|
}
|
|
First one makes sure that 'far_poi' is normalized, then far_poi
|
|
becomes a linear address, which makes it very difficult to use
|
|
it, because the possibility to get a segment warp gets very high.
|
|
-->
|
|
Change: add_far() also returns a normalized real mode pointer
|
|
as adjust_far() does.
|
|
Probably in DOS-C supporting various architecures thee functions
|
|
served other duties, but the current useage is highly dangerous.
|
|
bugfix: task.c: ChildEnv(): nEnvSize didn't counted the last '\0'
|
|
bugfix: task.c: ChildEnv(): Allocation: maximum absolute filename to
|
|
short and forgot the word counter
|
|
bugfix: task.c: ChildEnv(): for very corrupt environments, the
|
|
copy function failed.
|
|
bugfix: task.c: DosExeLoader(): If exe_size > allocated_size or
|
|
DosMemLargest() failes, the environment is not deallocated
|
|
bugfix: task.c: DosExeLoader(): Calculating the exe_size to be
|
|
allocated. At both places (+ header.exMinAlloc & ...MaxAlloc)
|
|
sizeof(psp) is added to exe_size. Why? image_size already
|
|
contains sizeof(psp).
|
|
chg: task.c: DosExeLoader()/DosComLoader(): MCB patching and command
|
|
line copying is no outside of those functions
|
|
chg: asmsupt.asm: _fbcopy: re-use parts of _bcopy
|
|
add: asmsupt.asm: fmemset, fmemclr, fmemclra {Replace the explicit
|
|
for() loops}
|
|
|

* change getblock so that it flushes all buffers for a drive when it

has to flush one of them to make room. This should speed disk
|
|
access slightly.
|
|
* Change the boot sector so there is a compile-time option to use
|
|
multi-sector IO or single-sector IO. The default is multi since
|
|
ror4 seemed to have fixed the problem we had before.

* Changed mainly the map_cluster function in fatfs.c so that instead
|
|
of starting at the beginning of the FAT chain every time, it will

be smart about it, and start at the last FAT location that it was
|
|
before if it can. This speeds up disk access considerably

especially on slower machines.

bugfix: ^Break handler according cmt1.txt
|
|
bugfix: DosCreat(): Detection for Devices and extension:
|
|
the semi-colon behind if(*froot) is definitely wrong, whether
|
|
one wants CON.EXT to be interpreted as CON or not.
|
|
bugfix: DosOpen(): dito
|
|
|
|
* Re-implementation of ^Break handler -- 1999/03/27 ska
|
|
+ Warning: The handle_break() function assumes that the InDOS flag
|
|
was incremented (except if ErrorMode is true). Never call
|
|
handle_break() unless the InDOS flag has been incremented within
|
|
this reentrant call of DOS.
|
|
|
|
+ ^Break is detected and handled at certain places within the
|
|
kernel only: a) within the CON: device when reading or writing a
|
|
character, and b) when entering the INT-21 service (if extended
|
|
break checking is enabled). At these places the process flow can
|
|
be modified to: either a) redo the interrupted function or b) abort
|
|
the currently running process.
|
|
|
|
+ Both actions are performed by switching back to the user stack
|
|
and enter INT-21 handler again. If to terminate the program, AX is
|
|
modified into 4C00h.
|
|
|
|
+ By default, if the user has no ^Break handler installed, the
|
|
program is terminated.
|
|
|
|
+ Heavy change: The original implementation installed an unique
|
|
INT-23 handler that directly called the actions performed
|
|
DOS-4C-XX. In fact, this was identically with when the user had an
|
|
own handler installed and returned the Carry flag set, except that
|
|
it was somewhat quicker, because the kernel need not decode the
|
|
4C00h command. Now the Carry flag is set prior the call of INT-23,
|
|
so the default action is to terminate the program.
|
|
|
|
+ Note: INT-23 is called with all registers as they are passed to
|
|
the INT-21 entry. When they are modified, they are passed
|
|
_modified_ to the API interpreter. This also allows the DOS1-style
|
|
termination by to load register AH with 0 (zero).
|
|
|
|
+ RBIL says:
|
|
"any DOS call may safely be made within the INT 23 handler,
|
|
although the handler must check for a recursive invocation if it
|
|
does call DOS"
|
|
This can be interpreted so or so, the problem is that the user can
|
|
call DOS again, what would overwrite the saved _usr_stack pointer
|
|
with a different value and, therefore, cannot be used to check if
|
|
INT-23 was returned by RETF or RETF2/IRET.
|
|
|
|
Because a recursive invokation of INT-23 is to prevented by the
|
|
user, the kernel could internally save SP to somewhere else.
|
|
However:
|
|
a) where?
|
|
b) is it reliable that the user ever returns from INT-23 at all?
|
|
|
|
The implemented method uses the same mechanism as fail-safe intr()
|
|
function is implemented: A little piece of code is constructed
|
|
within the stack, which contains the value of SP as an operand of
|
|
an immediate MOV instruction.

1999 Apr 13 - Build 2007

-------- ror4 (ror4@cryogen.com)
|
|
* The boot sector now moves itself to the last 512 bytes of
|
|
conventional memory instead of a lower memory location.
|
|
* The kernel startup code has also been modified so that it works
|
|
with the new boot sector.
|
|
|
|
1999 Apr 12 - Build 2007
|
|
-------- ror4 (ror4@cryogen.com)
|
|
* The directory scanning functions (`findfirst'/`findnext') now also
|
|
recognize more flavours of the volume label attribute byte (namely
|
|
0x09, 0x28 and 0x29).
|
|
* Subdirectories are now no longer assumed to have the same size as
|
|
the root directory.
|
|
* `device/device.lib' is now included as a dependency in the kernel
|
|
makefile.
|
|
* Removed several unused assembler modules from the `device/' branch
|
|
(see `device/device.mak').
|
|
|
|
1999 Apr 11 - Build 2007
|
|
-------- ror4 (ror4@cryogen.com)
|
|
* The kernel now reads times from the system clock (0x40:0x6c)
|
|
instead of the RTC. The RTC is only used during startup to
|
|
initialize the system clock. (As a side effect of this,
|
|
`ReadATClock' has been moved from `_TEXT' to `INIT_TEXT'.)
|
|
* Checking for leap years is now improved -- year numbers which are
|
|
divisible by 100 but not by 400 are not counted as leap years. (Not
|
|
that it matters for year 2000, though.)
|
|
* The scaling factor used to convert the system time count to a
|
|
second count has been changed from 18.2 to the more accurate (?)
|
|
19663/1080.
|
|
* Day numbers used by `clock$' are now 0-based (as in MSDOS) instead
|
|
of 1-based. Thus 1 Jan 1980 is now day number 0.
|
|
|
|
1999 Apr 10 - Build 2007
|
|
-------- ror4 (ror4@cryogen.com)
|
|
* Added code to prevent the kernel from returning path names
|
|
containing double backslashes.
|
|
|
|
1999 Apr 9 - Build 2007
|
|
-------- ror4 (ror4@usa.net)
|
|
* File handles are now cloned properly when a child process is spawned.
|
|
* The `DosClose' function now also frees SFT entries corresponding to
|
|
devices, not only those entries corresponding to files.
|
|
* Removed a (minor) memory corruption bug in the code for int 0x21,
|
|
ah = 0x09.
|
|
|
|
1999 Apr 6 - Build 2007
|
|
-------- ror4 (ror4@cryogen.com)
|
|
* Functions ax = 0x5700 and 0x5701 (get/set file date and time) now
|
|
return the right values at the right times. (They used to return
|
|
success when there's an error, and return error when there's a
|
|
success.)
|
|
* Removed the `/k' switch to the linker in `sys/sys.mak'.
|
|
|
|
1999 Apr 4 - Build 2006
|
|
-------- John Price (linux-guru@gcfl.net)
|
|
* added "version=" directive so that you can change the version that
|
|
the kernel reports. Usage: version=<major>.<minor> (i.e.
|
|
version=6.22)
|
|
|
|
1999 Apr 4 - Build 2006
|
|
-------- ror4 (ror4@usa.net)
|
|
* Fixed the file name parsing function (`ParseDosNames') so that it
|
|
handles single-character path names correctly.
|
|
* Also modified the functions which call `ParseDosNames' to check its
|
|
return value instead of assuming that it is always successful.
|
|
(This is not currentl useful, but it will be when error checking is
|
|
introduced into `ParseDosNames'. In other words, there'll be more
|
|
changes to `ParseDosNames' in the near future...)
|
|
|
|
* After wondering for a long time why the kernel text segment was
|
|
always getting corrupted when I ran DJGPP `bash' 1.14.7, I finally
|
|
decided to examine the code occurring before the handler for int
|
|
0x21, ah = 0x60, and I found out why... :)
|
|
* Fixed the problem of int 0x21, ax = 0x5d06 causing memory
|
|
corruption.
|
|
* Corrected the types of `internal_data', `swap_always' and
|
|
`swap_indos' in `kernel/globals.h'.
|
|
|
|
* Improved checking for invalid file names in `ParseDosName'
|
|
(although I'm still not sure whether the check is water-tight or
|
|
not).
|
|
* Changed the default path setting from `PATH=' to `PATH=.'.
|
|
|
|
* Output from character I/O functions now goes to standard output as
|
|
it should, instead of the console. Also, there's now a clear
|
|
distinction between console input/output and standard input/output.
|
|
* Tabs are now expanded during writes to the console device.
|
|
* Removed a hard-wired limit on the number of entries in a JFT.
|
|
(Although I'm not sure whether this is really correct...)
|
|
* Many other changes to the file descriptor handling code.
|
|
|
|
1999 Mar 29 - Build 2006
|
|
-------- John Price (linux-guru@gcfl.net)
|
|
* Changed boot loader so it prints some feedback info while booting.
|
|
Removed code to handle FAT12 and FAT16, and code to calculate the
|
|
start of the fat, rootdir, and data. Moved these functions into
|
|
the sys command. Now there are two versions of the boot loader
|
|
created, one to handle FAT16, and one for FAT12. These are
|
|
hard-coded into the sys command, so the need for the boot.bin file
|
|
is obsolete.
|
|
* created a new program (bin2c) to convert the boot loader binary
|
|
file into a header file that can be included in the sys program as
|
|
an array of bytes.
|
|
|
|
1999 Mar 29 - Build 2006
|
|
-------- ror4 (ror4@usa.net)
|
|
* Changed the class of `_BSSEND' from "STACK" to "BSS" in the
|
|
`drivers/' branch (which I forgot about in my last patch).
|
|
* Removed all traces of the `CONST' segment, since it was causing
|
|
`IGROUP' to be assimilated into `DGROUP', which shouldn't happen.
|
|
* Added a `(void)' cast to the `setvec' macro in `kernel/globals.h'
|
|
(`setvec' no longer returns the original ISR vector).
|
|
* Changed an incorrect error message in `sys/sys.c'.
|
|
* Removed `drivers/setvec.asm', since it's no longer needed.
|
|
* Also removed `kernel/krnstart'.
|
|
* The name field in a process's MCB is now filled in the same manner
|
|
as in MSDOS -- instead of being padded to the right with spaces, it
|
|
is now terminated with '\0'. Also, if the original file name
|
|
doesn't have an extension, the code will stop copying the file name
|
|
at '\0' instead of continuing to look for a '.'.
|
|
* Fixed the problem of the `switchar' syscall (int 0x21, ax = 0x3700) not
|
|
returning the correct value.
|
|
|
|
|
|
1999 Mar 28 - Build 2005
|
|
-------- ror4 (ror4@usa.net)
|
|
* Removed the need for `ipl.sys'. (!) The kernel makefile now
|
|
statically relocates `kernel.exe' to 0x60:0 and outputs the
|
|
resulting binary to `kernel.sys', and the boot sector has also been
|
|
modified to load `kernel.sys' at 0x60:0 instead of `ipl.sys' at
|
|
0x2000:0. (I chose 0x60:0 because it's the first 512-byte boundary
|
|
occurring after the BIOS data area, 0x40:0.) Finally, `sys.com' has
|
|
also been updated.
|
|
|
|
* Also changed the boot sector code in some other ways. In
|
|
particular, because `kernel.sys' is rather large, I had to add some
|
|
code to move the boot sector away from 0:0x7c00 to somewhere
|
|
higher. (For 640K systems the boot sector will be shifted to
|
|
0x6000:0x7c00. However, there may be problems on systems with very
|
|
little conventional memory -- I'll probably look into this later.)
|
|
|
|
* Made some minor changes to the assembler source files so that they
|
|
can compile on `masm'. (JP: The code still compiles fine with tasm
|
|
too).
|
|
|
|
* Also changed several incorrect label references in the assembler
|
|
sources. (JP: These changes fixed the "Fixup" errors we been
|
|
talking about in the list)
|
|
|
|
* Eliminated redundant re-makes of files in the various makefiles.
|
|
For one thing, `*.cfg' files are no longer generated from the
|
|
makefiles, but are independent from them. (I didn't like the idea
|
|
of having to compile an entire branch each time I edit a
|
|
makefile...) Also, intermediate files are now retained instead of
|
|
deleted.
|
|
|
|
* Also made some changes to `build.bat' (you'll know them when you
|
|
see them).
|
|
|
|
* Added a file `lib/libm.mak'
|
|
|
|
* Added a file `kernel/krnstart
|
|
|
|
* The code required to initialize the kernel (or rather most of it)
|
|
is no longer retained in memory after the initialization process is
|
|
done. I accomplished this by moving most of the initialization code
|
|
from `_TEXT' to a new segment named `INIT_TEXT'. Of course, I also
|
|
had to introduce lots of other changes in order for everything to
|
|
compile and run properly:
|
|
- Added code to `kernel/src/kernel/kernel.asm' to move the contents
|
|
of `INIT_TEXT' to the top of conventional memory and continue
|
|
from there. Control is only transferred back to `_TEXT' when the
|
|
kernel calls `p_0'.
|
|
- Many functions are called from both `_TEXT' and `INIT_TEXT'. To
|
|
fix this, I created far wrappers for these functions which can
|
|
then be called from `INIT_TEXT'. (E.g. for `execrh' there's a
|
|
corresponding far function named `init_call_execrh' which simply
|
|
calls `execrh' with its own parameters.) One exception to this is
|
|
`printf' -- instead of creating a far wrapper for a near
|
|
`printf', I created a near wrapper for a far `printf' (now called
|
|
`init_call_printf'), because it was easier that way. :)
|
|
- Most functions which are required only during initialization time
|
|
were shifted into `INIT_TEXT'. (There are still some functions
|
|
which should rightfully go into `INIT_TEXT', but are retained in
|
|
`_TEXT' as far functions, because I found it too difficult to
|
|
move them out. :( ) Because Turbo C only allows at most one code
|
|
segment to be defined for each module, I had to shift some
|
|
functions around within the source tree -- the file
|
|
`kernel/src/kernel/proto.h' says it all.
|
|
- A cosmetic change mentioned here for completeness: all functions
|
|
defined in `INIT_TEXT' are now marked with the word `INIT' (in
|
|
fact a null macro) so that the reader can easily distinguish them
|
|
from functions defined in `_TEXT'.
|
|
|
|
* Replaced `exit' calls with `for (;;);'.
|
|
|
|
* Changed `strcpy' into a macro which calls `scopy'.
|
|
|
|
* Also redefined `setvec' to be a macro (I didn't want to waste time
|
|
writing a far wrapper for it).
|
|
|
|
* Removed the `break_key' function in `kernel/src/kernel/kernel.asm'.
|
|
|
|
* `low_int25_handler' and `low_int26_handler' are now of type
|
|
`void interrupt far()' instead of `void near()'. (I hope I updated
|
|
`entry.asm' correctly -- I never tested `int 0x25' and `int 0x26'...)
|
|
|
|
* Changed the class of `_BSSEND' from "STACK" to "BSS" -- "STACK" is
|
|
now used for a separate stack segment (`_STACK').
|
|
|
|
* Assembler modules now include `segs.inc' instead of having their
|
|
own long list of segment definitions. (Some day I'll update the
|
|
makefile dependencies to reflect this.)
|
|
|
|
* Also made a few minor changes to the assembler modules so that
|
|
`masm' won't complain.
|
|
|
|
* Changed the `-X' switch in `kernel.cfg' to `-X-', so that I don't
|
|
have to worry about C module dependencies.
|
|
|
|
* Removed the definition of `CFLAGS' from the makefile -- everything
|
|
is now in `kernel.cfg'.
|
|
|
|
* Created a file `kernel/src/kernel/init-mod.h' which is included by
|
|
modules whose code is supposed to go into `INIT_TEXT' instead of
|
|
`TEXT'.
|
|
|
|
* This diff solves the problem of the MCB of a process not having a
|
|
correct value in its name field (bug report #6).
|
|
(The definition of the `toupper' macro is because I shifted the
|
|
`toupper' function into `INIT_TEXT' a while ago, and therefore
|
|
can't be called from `_TEXT' now...)
|
|
|
|
|
|
-------- John Price (linux-guru@gcfl.net)
|
|
* Made changes so you can create a directory with the same name as a
|
|
volume label, but you still can't rename or delete it!
|
|
|
|
* Fix findfirst and findnext functions so that act as they should.
|
|
(i.e. If the attrib has only the volume label set, then it returns
|
|
the volume label entry in the root directory, else it returns the
|
|
files/directories that are specified with the attrib, ignoring the
|
|
read-only and archive bits (these are always returned).
|
|
|
|
* reorginize the source tree. Removed IPL directory, and command.
|
|
Moved all the file system C files into the kernel directory.
|
|
Modifed build.bat, clean.bat, and all the make files to reflect the
|
|
new tree.
|
|
|
|
* changed so that kernel will look for a "fdconfig.sys" file, and use
|
|
it INSTEAD of config.sys. If it does not find it, it will look
|
|
for, and read config.sys, if it exists.
|
|
|
|
* Fixed so that if you call an INT 21 function with AH containing a
|
|
unsupported function, the carry flag is set.
